Camera Accessory Adapter With Dual-Interface Mounting Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems face issues with erroneous mounting of accessories due to incompatible flange focal distances, leading to misalignment of optical images, and existing solutions increase manufacturing costs and complexity.
Innovation Solution
An adapter device with specific mount configurations, including claws and recesses with controlled angular ranges and biasing members, ensures secure attachment and detachment of accessories to imaging apparatus, preventing erroneous mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an accessory with incompatible flange focal distance is mounted to a camera, then the mounting system allows connection, but optical image alignment deteriorates
Solution Approach 1:
The patent applies preliminary anti-action by providing protrusions on the camera body that abut against wall portions on the accessory before full mounting occurs. This preliminary mechanical interference prevents accessories with incompatible flange focal distances from being fully mounted, thereby preventing optical image misalignment while maintaining mounting compatibility for correct accessories.
2Manufacturing precision
If a wall portion is added to the camera body to prevent erroneous mounting, then mounting precision improves, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the protective function into existing structural elements. The protrusions are integrated into the camera body's mounting structure, and the wall portions are incorporated into the accessory's mounting interface. This combining of protective features with existing structural components achieves mounting precision without significantly increasing device complexity or manufacturing cost.
3Adaptability or versatility
If a conversion adapter is inserted between camera and accessory, then flange focal distance compatibility is achieved, but erroneous mounting risk increases
Solution Approach 1:
The patent applies preliminary anti-action at both interfaces of the conversion adapter. The camera-side protrusions abut against wall portions on the adapter, and the accessory-side protrusions abut against wall portions on the adapter. This dual preliminary interference ensures that erroneous mounting is prevented at both connection points, maintaining reliability while achieving flange focal distance compatibility.

AI summary
An adapter device includes a first mount and a second mount. The first mount is fastened to the adapter device by multiple screws, and has first through third mount recesses and first through third mount claws disposed following a circumferential direction. The second mount is fastened to the device by multiple screws, and has fourth through sixth mount claws and fourth through sixth mount recesses disposed following the direction. The first through third mount claws are insertable to mount recesses on an imaging apparatus, the fourth through sixth mount claws are insertable to mount recesses on an accessory, and the smallest angle range of the first through third mount recesses in the direction of the first mount is not greater than the smallest angle range of the fourth through sixth mount claws in the direction of the second mount.
